Holes in the exhaust before the cat will cause a huge increase in NOX.

holes in the exhaust cause for the tail pipe sniffer to read that it is diluted and wont run the dyno test if it cant get a proper reading

When you have holes in exhaust,bad vacuum lines etc. fix that stuff before you test the first time, it will save you time and money........SANTA
thats why im trying to get this done lol!!! its a 90 limited. the other thing is that they said i cant have it tested with the lockers in the axles. which is also total b.s.!!! i need to find the schematic for the vacuum lines. i should get ngks or iridiums for spark plugs?

Champion truck plugs, Quality gas, and sea foam or lucas fuel treatment. There aren't that many vac hoses that I remember, shouldnt be to hard to trace meassure and replace.

The jeep God (MJR) says to use OEM plugs only. I spray starter fluid on the vacuum lines on a running engine and listen for RPM change to test for leaking vacuum lines( Fire X close by)......SANTA

I feel your pain. It's time to smog our '89.
Don't forget the pre-heater hose from the exhaust to air cleaner.
Gas caps often need replacement if the gasket doesn't seal.
Don't mention the lockers, it doesn't matter and they don't need to know.
I found a schematic for the vacuum lines around here a few days ago and copied it. If you can't find it send a note and I'll email it to you.
The vacuum bottle is only used for the heater and cruise (if you have it), it shouldn't matter for smog.

yea the locker thing is a complete lie unless their roller setup is lame.
I picked up NGK V power spark plugs for about $4 each at auto zone. I like em and if you search, you'll see that many prefer either NGK, Champion, autolites. Dont get those stupid e3 plugs

Now that you have the schematic you could go to the junk yard and pull all the lines you need. I picked up the full set of emission lines and vacuum bottle with lines plus TPS, IAC and a few other three letters items for under $20-. Heat shrink tubing can help splice the lines.
